摘要：We consider the split convex feasibility problem in a fixed point setting.Based on the well-known CQ-method of Byrne (2002), we define an abstract Landweber transformation which applies to more general operators than the metric projection. It turns out that the Landweber transformation preserves many interesting properties. Moreover, the Landweber transformation of a (weakly/linearly) regular mapping is again (weakly/linearly) regular. These regularity properties are relevant because they lead to(weak/linear) convergence of many CQ-type methods.
